JOSEF WE/DE/VBACI/ER flttarnus Patented Feb. 16, 1932 UNITED STATES JOSE! WEIDENBACHEB, O1 AUGSIBUBG, GERMANY PORTABLE SHED STRUCTURE Application filed Kay 29, 1930, Serial No. 457,417, and in Germany November 80, 1928.

Present day shed buildings show various deficiencies. The solidly built type may have smooth walls which on the inside may be decorated in any desired manner, they are also heat and soundproof, but the cost of their erection is high owing to the lon time it takes to erect them and the relative y expensive building material. Once erected they cannot be taken apart again and transported to to any other place. The portable kind on the other hand take less time to erect, but

they are neither heat nor soundproof. Nor

are their inner walls of the desired smoothness; on the contrary, structural details which 5 prevent a full utilization of the enclosed space remain visible everywhere.

The latter deficiencies of the cheaper and more common iron or wooden structures are particularly objectionable in cases where such an sheds are intended to serve for the housing of exhibitions or for concerts and festivals, or as town halls, art galleries, meeting places, for indoor sports or gymnastics, swimming or other baths, or skating rinks. They are -r also liable to defects due to the formation of condense water. Sound insulation is also quite insufiicient as there is no air cushion to deaden the noises penetrating from without or within. rm The main object of this invention is to obviate the above-mentioned drawbacks and to provide a portable shed structure, the interior of which is adequately insulated with respect to heat and sound.

A further object is to provide a portable shed structure, wherein the upper parts of the inner rods and the cross rods are connected by a transparent material forming ceiling windows, so that the shed interior receives a suflicient amount of light.

For that purpose the portable shed structure, according to this invention,is composed of outer rods, inner rods, girders and cross bars arranged in such a way that they form l5 together with the wall linings and the roof linings an air cushion adapted to act as an insulation with regard to the heat and sound transmission.

The portable shed structure made accord- 0 ing to this invention may be also used for fair structures, coach-houses, refrigerating chambers, station buildings, halls for airplanes and airships, ateliers, theaters and similar buildings, work shops of all kinds, for instance, those wherein a constant temperature must be maintained, mortuaries, hothouses, churches, temporary buildings used in warfare and in cases of emergency and so on.

Fig. 8 is a cross section of a shed on a larger scale.

, The hatched portions of the drawingsrepresent the air cushion, dotted lines the glass skylight and the flat lines outer and inner 5 walls, in section.

The substructure of the novel shed building consists of any desired number of iron trusses disposed in pairs opposite one another and at intervals one behind the other or, as in the case of a central shed, along the sides of a square, (as shown in Figs. 1, 2, 3, 5 and 7) of about the shape shown in Fig. 1, the angle at being selected with due regard to the destination and also the required height and span of the building. The novelty of the construction of the truss is in the first place to be found in the outlines of the truss (see Fig.

1, normal truss and Fig. 2, variety of same) the characteristic feature of which will here next be described.

The outerrods (d) arevertical and form also the substructure for the skin which may be fastened thereto directlyor by means of intermedial rods; the skin being plates or slabs of metal or stone (slate, eternit or similar material). a

The inner rods (6) of the truss are inclined towards the interior and lead in a straight (Fig. 1) or slightly broken line (Fig. 1

2) from their tracing points A and C through the roof to the crown. The lower part of these inner rods is not only supporting struc- Y ture but also substructure for the inner walls (A-D and G-C) which run parallel to the outer walls and may be made of light structure planks, such as the material known as celloteX. The part of the inner rods (BE Truss rods HE and FJ serve as sub- 7 structure of the fiat roof, which roof may be made of the same material as the outer walls.

A shed according to this invention either with or without lateral naves (Figs. 2 and 5) may be advantageously used as a church.

If the spans are too great, two or more sheds may be combined in a way shown in Fig. 7. The inner intermediate rods h are coated on all sides with light planks, similarly to the interior Walls (Fig. 7

A number of wind-struts depending on the particular construction and the dimensions of the shed is inserted within the interior walls and obviously on the interior sides thereof, said wind-strutsbeing arranged in diagonals and in the vertical planes HD and GJ in diagonalscrossing each other (Fig. 4;). V

The number and the distribution of the intermediate rods 0 depends on the dimensions of the shed, the employed trusses and the prescribed statical standardized regulations.

The following advantages are gained by the described disposition of walls and double skylights.

The windowless smooth inner and outer walls are easily kept in good repair; the light streams evenly into the building from the top, heavy shadows arethereby avoided the light rays f) illuminate walls and floor evenly and brightly so that no portion of the interior lies in the shade.

Central sheds made according to this invention have a great amount of light. In the modification shown in Fig. 6 the vertical projection of the upper light amounts to about 30% of the shed plan surface.

In winter the outer skylight in consequence of its steepness keeps free from snow and never needs to be cleaned.

Inside the building the walls are perfectly smooth, none of the substructure being visible and the plates or slabs forming the inner and outer walls maybe fixed to the substructure without the use of expensive and complicated scaifolding as, starting from the bottom, by the aid of a simple flying scaffold they may easily be screwed or nailed on to the trusses (Fig. 3, e e e a The smooth inner walls admit ofany kind of decorative treatment. Owing to their slant, dust cannot cling to the surface.

Foundations are necessary only for the tracing points of the trusses A, C, and so on; there is no need for foundation walls, which circumstance cheapens the erection and is also of advantage in cases where the condition of the foundation soil is unsuitable. When a central hall is being built the trusses are placed along the sides of a square or a rectangle, as already mentioned. A central shed may be erected on as few as four tracing points of force (Fig. 6, A, B, C and D).

The layer of air between the inner and outer walls is continuous and of great depth conv sequently disturbing noises will effectivelybe stopped from penetrating into the structure; at the same time the air cushion will prevent music made inside the building to be heard outside.

The acoustic properties of the structure will, because of the air cushion, also be eX- cellent."

The air cushion will also prove to be a first rate heat insulating means. This renders the structure equally suitable for use in tropical countries, forskating rinks or cold stores and as a heatable meeting place also for the taking of talking films, but especially for swimming baths, as there is no danger of the structure getting damaged through condensed water. I

None of the transportable sheds known in prior art have the advantages of a shed according to this invention, i. e. complete insulation with respect to heat and sound and completely smoothinterior wall surfaces.

The novel shed structure may be erected in much less time than a shed'of the solid type and although throughout cheap material may be used and its cost is about 40% less, it possesses the same valuable properties as those, viz high stability, durability, heat and sound insulation, brightness and clearness of disposition of the interior space. In consequence the novel shed may be compared only to solid shed structures and not to the ordinary portable kind which are neither sound nor heat proof. have no smooth walls but on the contrary display, everywhere their unpleasing structural details.

In addition to the advantages already enumerated the'novel shed offers the great'advantage as against solid sheds, that they may be pulled apart and re-erected' elsewhere without loss of material.

Number and disposition of the rods (0) will'in every case be ascertained by known statical rules.
